随着上海城市高架道路里程不断增加,公路路网逐步建成。城市高架路交通安全问题也日益凸显,并已经成为社会各界高度关注的热点问题。通过排查高架小半径匝道安全隐患路段,分析事故原因,结合日常运行、养护等方面的经验,初步探讨了小半径匝道安全隐患路段优化改造方案,以提高高架道路运行安全及养护管理水平。
As Shanghai’s urban elevated road mileage continues to increase, the road network has been gradually built. Urban elevated road traffic safety issues are also increasingly prominent, and has become a hot issue of great concern to all sectors of society. By investigating the road sections of elevated ramp with small radius and analyzing the causes of the accident, and combining with the experience of routine operation and maintenance, the optimization and reconstruction of road sections with small radius ramp are discussed to improve the operational safety and maintenance management of elevated road.
